Top 10 Potassium-Rich Foods And Their Benefits
Potassium is an essential mineral that plays intrinsic roles in maintaining human health, yet many people are deficient in this nutrient, despite its abundant availability in many different foods. Potassium acts as a critical electrolyte in the body, but it is also found within every single cell, while also helping to regulate the levels and intake of other critical nutrients.
The recommended amount of potassium intake is approximately 4.7 grams every day. However, majority of men consume only 3 grams and women consume even less – 2.5 grams, on an average. Due to the essential nature of this mineral, a constant deficiency can significantly lower your overall health over time.
It is important to maintain steady levels of potassium because a deficiency as well as an excess can lead to hypokalemia and hyperkalemia, respectively, each of which comes with a number of unpleasant side effects, including anything from stomach upset and muscle cramps to an irregular heartbeat and even death.
